"Someone needs to be the audience," my mother once told me. She was comfortable with being an introvert. Annie Carson, in To Win A Wallflower is an introvert. Barrett, the hero, is most likely a quiet extrovert. A man who enjoys going boxing and being in the fight would probably have to be extroverted. The biggest extrovert I've written about was Beatrice in The Notorious Countess. I had nothing to do with calling her Notorious. I did choose Beatrice the Beast as her nickname though, but it was a name she didn't deserve. Foxworthy, in Redeeming the Roguish Rake was another extrovert, and the heroine, Rebecca, was an introvert even though it wouldn't have been noticed while she was in the countryside. Her quiet nature did give her grief after she moved to London. But Foxworthy was aware enough not to try to change her to something she wasn't. I don't set out to write a character who is an introvert, or one who is an extrovert. I just write a person who hasn't yet found their happy ending.
